It looked good, but just to check I copied your code and pasted it into the challenge and it worked fine. You're right, there's nothing wrong with it.

You may try closing the browser and reopening it. Another step would be to disable the cache. I've had a few experiences like yours where the right answer wasn't accepted because of a wrong answer earlier.
